hello i have recently bought a new motherboard the abit I-G31 and a cpu the intel duel core e8500 i put the motherboard into my old computer case and used all of the old components of my old motherboard like ram ,HDD ,cd drive, and the psu.
so i press the power button and the led for the button turns it beeps , you can hear the fan is on but there is no video output i have tried using both my pci graphics card and the onboard graphics card so i dont think its the the graphics cards.
these are the components

abit I-G31 motherboard
intel core2 duo E8500
2X 1gb 2**mhz ddr2 ram (i think this may be the problem as the mobo states it supports 800/667)

so yeah thats the problem i think it is because of the ram but i don't want to go buying any just yet before i know for sure what the problem is.

cheers in advance if anyone can help me and sorry for wasting time if its just an obvious answer.
